Application filed March 9. 1918.

To all whom it may concern:

Be it known that I, LOUIS V. ARONSON, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Matches, of which thefollowing is a specification.

This invention relates to matches, and more particularly to a typehaving certain characteristics which render them particularly desirablefor outdoor use, as stated in my Patent 592,227.

One of the objects of the present invention is to provide a match of theabove general character which will have a relatively long steady periodof combustion. Another object is to provide a match which may be easilyignited by friction on any surface, either dry or damp, and possessqualities of persistent combustibility, that is one which will continueto burn even in a high gale ofwind. A further object is to provide amatch which will be waterproof or unaffected by moisture. A furtherobject is to provide a match free from poisonous and objectionable fumesand which, after the period of combustion, will immediately go outwithout leaving any hot or glowing end. A further object is to provide amatch of the above general character which may be safely handled andeasily and inexpensively manufactured.

A further object is to provide a match which will not give off sparkswhen ignited, thereby making it safer to handle around explosives.

Other objects will be in part obvious fromv the annexed drawings and inpart indicated in connection therewith by the following analysis of thisinvention.

This invention accordingly consists in the features of construction,combination of parts and in the unique relations of the memhers and inthe relative proportionin and disposition thereof, all as morecompletely outlined herein.

To enable others skilled in the art so fully to comprehend theunderlying features thereof that they may embody the same b the numerousmodifications in structure and relation contemplated by this invention,drawings depicting a preferred form have been annexed as part of thisdisclosure, and wherein is showndiagrammaticaliy an enlargedlongitudinal sectional View of the match.

Specification of Letters Patent.

Patented Dec. 17, 1918.

Serial No. 221,478.

A match of the above character is preferably made from a stick tippedwith a composition of certain potassium salts, phosphorus and lampblack, with a suitable binder, and provided with a waterproof coating. Ipreferably use one part of potassium chlorate and two parts of potassiumnitrate. mixed with substantially sixty parts of amorphous phosphorusand sixty parts of lamp black. The potassium chlorate which may beconsidered as having a relatively high oxygen content, and the potassiumnitrate having a slightly lower oxygen content, may be varled withinreasonable limits, as may be desired, as one in a way counteracts theother when combined in the presence of lam black and phosphorus, toprovide a relative y slow burning fuse, or match, as distinguished froma more nearly explosive combustion. The lamp black which forms a basehas the peculiar characteristic of being relatively non-combustible, andafter the potassium salts and phosphorus have burned out, the lampblack, which protects the wood upon which the combustible material ismounted. will absorb the heat, thus allowing the flame to die outsuddenly without leaving a dangerous glowing or hot end.

The above-referred to ingredients are mixed in the presence of anydesired amount of water and twenty parts of dextrin to form a paste ofthe desired consistency. whereby when the stick is dipped into the pastethe combustible composition will adhere thereto in the desired amount.

In the accompanying drawing, 2 denotes the body of the match which ispreferably formed of wood, while 3 indicates the combustible compositionabove referred to.

It will be noted that this composition extends along the body 2 such adistance as to insure a steady even flame for a period of two to fiveseconds. as may be desired. The period of combustion however may bevaried somewhat by changing the proportion of potassium salts. as wellas by the length of the body-portion which is covered by thecomposition. After the combustible material 3 has set. the match is thenpreferably provided with an easily ignitible material 4: as shown in myprior patent and treated with any suitable waterproofing solution 5,such for example as shellac or a cellulose solution.

match constructed in the above manner and with the herein statedingredients is particularly adapted for outdoor use and not only formsan important item of the equipment of soldiers engaged in trench warfarefor lighting the fuses of bombs and hand grenades in windy and dampweather, but is also of great value to sailors, hunters and campers wholive outdoors, frequently requiring the use of matches under conditionsin which ordinary matches.

cannot be used.

It is believed that from the above it will be seen that the presentinvention provides a match of simple and practical construction adaptedto accomplish, among others, all of the objects and advantages hereinset forth.

The nature of the compound employed by me is such that it adds to thefacility with which the match may be ignited. It is also of such anature that the head of the match as a whole will crumble and not igniteunder pressure applied longitudinally of the head.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. A match of the character described consisting of a stem provided witha head ignitible by friction, having the properties of persistentcombustibility, said head being madeof a composition including a Irelatively small per cent. of oxygen carrying potassium salts mixed witha much larger per cent. and substantially equal parts of phosphorus andlamp black in the presence of a suitable binder.

2. A match of the character described consisting of a stem provided witha head ignitibleby friction, having the properties of persistentcombustibility, said head being made of a small per cent. of oxygencarrying potassium salts with a relatively large per cent. of phosphorusmixed with a substantially equal part of non-glowing material.

3. A match of the character described consisting of a stem provided witha head ignitible by friction and consisting of a small per cent. ofoxygen carrying potassium salts with a relatively large per cent. ofphosphorus mixed with a substantially equal part of non-glowingmaterial, said parts being mixed with a suitable binder and covered witha waterproofing composition.

4. A match of the character described consisting of a stem provided witha head ignitible by friction, said head consisting of a mixture of onepart of potassium chlorate, two parts potassium nitrate, sixty partseach of lamp black and phosphorus and twenty parts of dextrin, and allcovered with a suitable waterproofing composition.

In testimony whereof I aflix my signature.

Louis v. ARONSON.
